SCHEDULED MAINTENANCE LOG Determining Your Maintenance Interval: Months vs. Mileage Lexus recommends obtaining scheduled maintenance for your vehicle every six months or 5,000 miles, whichever occurs first. For example: • If at six months you have driven less than 5,000 miles, you should obtain maintenance at six months; don't wait until 5,000 miles. • If you drive 5,000 miles in less than six months, you should obtain maintenance at 5,000 miles; don't wait until six months. Be sure to keep an eye on your mileage so that you obtain maintenance when recommended. If you are a low-mileage driver, mark your calendar to remind yourself to obtain maintenance every six months. Special Operating Conditions In addition to standard maintenance items, vehicles that are driven under special operating conditions require further maintenance service. These special operating conditions, which put added demands on a vehicle, include: • Driving on dirt roads or on dusty roads • Repeated trips of less than five miles in temperatures below 32° F or 0° C • Extensive idling and/or lowspeed driving for long distances, such as police, taxi or door-todoor delivery use If you drive primarily under any of the conditions noted, you should replace the engine oil and oil filter every six months or 5,000 miles. Some of these special operating conditions require other maintenance items; these items are indicated in each maintenance chart. MAINTENANCE 44 Scheduled Maintenance Log
